Detailed explanation-1: -Hydroelectric is when water is used to produce electricity. Water stored in a dam possesses potential energy and once the water starts falling, it has kinetic energy. When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower.
Detailed explanation-2: -What is Hydropower? Hydropower, or hydroelectric power, is one of the oldest and largest sources of renewable energy, which uses the natural flow of moving water to generate electricity.
Detailed explanation-3: -The kinetic energy of water is when it is rushing through a river, down a waterfall or through a hydroelectric power plant. The force of the kinetic energy is dependent on the height and mass of the falling water. Hydroelectric is when water is used to produce electricity.
Detailed explanation-4: -The water behind a hydroelectric dam stores gravitational potential energy since it is at a higher level than the water on the other side of the dam. As the water falls, this potential energy is converted into kinetic energy, which turns turbines to generate electricity.
